It shouldn't make any difference, since that is all hardware-level stuff. The only exception is that Valgrind doesn't yet support SSE3 instructions, and I think there are some hyperthreading-related instructions in SSE3? N |

It doesn't seem to make any difference in our case. We have dual-CPU Xeon boxes with hyper-threading enabled and valgrind works just fine here. Dimitri |
